SPECIPCATION forming part of Letters Patent No. 385,231, dated June 26,1888. Application tiled November 8, 1887. Serial No. 254,632. (Nomodel.)

To all whom it may concern.-

Be it known that I, JULIUs ARMIN Bresse- GER, a citizen ofthe UnitedStates of Amerithe city, county, and State of New York, have inventedcertain new and useful Improvements in Planes, of

which Vthe following is a specification.

The present invention relates to planes, and particularly torabbet-planes, the object whereof being to insure accuracy in theoperation thereof, and otherwise increased efficiency therein; and itconsists in the construction and combination of parts, all substantiallyas will be hereinafter fully described,and pointed ont in the claims. i'

In the accompanying Vsheet of drawings, Figure l is a side view of aplane comprising the present invention. Fig. 2 is a plan view of same.Fig. 3 isa central vertical section of the plane on line 3 3 of Fig. 2.Fig. 4 is a horizontal sectional view in detail on line 4 4, Fig. 3.Fig. 5 is a plan viewvof a portion of the face of the plane. Fig. 6 isa' section on line 6 6, Fig. 3.

ln the drawings, A represents the plane body or stock, having plates Bat each side thereof, covering the whole area thereof, except at theportion a, at and over the planethroat C.

D is a throat-platc adapted to be movable, as hereinafter explained, andE is the planeiron, having cutting-edge Z, as usual in planes.

F is the plane-iron holder, which has a 'transverse rib, d,corresponding and closely fitting a transverse groove,f, intheplaneiron. The upper end ofthe plane-iron holder is provided with aright-angled lug or ear, g, through the inner screwthread of which ascrewthreaded bolt, F2, engages. This bolt F2 has a head, 7L, which liesin a recess, K, at the rear of a lug, Z, in the casting, and the shankof the sorew-bolt F2 plays loosely through a hole, m, therefor insaidlng Z. The head of the bolt F2 is milled, and at each side projectsthrough apertures K in theside plates, B, of theplanestoelaand maybeconveniently turned by the hand to project or withdraw the edge of theplane-iron at'the throat, as is plain.

G is a block which bears on the upper side of the plane-iron, and it hasa tongue, p, projeeting upwardly in the inner recess of the plane-stock,through which is a slot, q, having a direction perpendicular to theplaneiron E, through which slot is passed a stationary pin, r, extendingfrom side to side of the plane-stock. Above the stationary pin r, andbearing on and between it and the upper wall of the slot q, is a spiralspring, s, which tends to force the block G upwardly away from theplane-iron. Resting over and 'upon thecdge of block G is a Camdisk, J,pivotally hung in the plane-stock, as atj, having a handle-arm, J2, andall so arranged that when said arm is swung downwardly, as shown, itwill of itself so remain until swung upwardly from the plane-iron E,allowing same,through the turning of the screw-bolt, to be altered inits projection, or to be removed, as desired.

The throat-plate D has its outer face of the same width as the face ofthe plane-stock, and it has a tongue or upward projection, K2, extendinginto the open space w, formed in the stock A. Extending through theparte ofthe stock is a screw-threaded bolt, L, which engages the femalescrew-threads of the upward extension K2 of the throat-plate D, and theend of the screw-bolt L is supported in a socket, to2, in the part m ofthe stock, as seen in Fig. 3, said bolt being prevented fromlongitudinal movement in one direction by the end of socket 2v2, and inthe other direction by its abutment against the plate M, secured on theend of the planestock. lllhe plate M, however, has a hole, w3, ofdiameter smaller than that of the bolt L, opposite such head, throughwhich a screw-driver or wrench may be inserted to engage with thescrew-slot. By turning the screw-bolt in one direction the throat'plateis moved toward the plane-iron to contract the opening or throat C, andwhen turned in the other direction the throat-opening is thus widened.

M2 M2 are pointed blades or groovers which are located at opposite sidesof the plane in longitudinal lines coincident with the outer edges orcorners of the plane-nomas shown in plan view, Fig. 5, in advance of theplaneiron. These blades are adapted and intended tobe projected adistance beyond the face of the plane as great at least as theprojection beyond the face of the plane of the plane-iron,

and in the operation ofthe plane, in the usual manner, the blades M2 M2form parallelgrooves or demarkations, exactly within and between whichthe cutting plane-iron E follows and cuts the shaving.

The grooving-blades Ml M2 extend through dovetailed grooves a2 in thethroat-plate, and are beveled or dovetailed on their edges, fitting thedovetailed grooves in the throatplate. There is also a clamp, N, forreceiving each grooving-blade, having inner dovetailed grooves, cl2,corresponding to the dovetail shape of the blades M2. The clamps N2 areadapted to be drawn inwardly, carrying the blades M2 therewith in atransverse line of the plane and firmly against the stock at its portionas above and below the clamp N, and inwardly against the inner wall,ofthe grooves in the throat-plate, and this inward bind of thegrooving-blades 'is secured by the screw-pin O, differentiallyY threadedat its opposite end portions z, having intermediate of its length asquared portion, z2, by which a permanent or other wrench-arm, I),engages, the turning of which screw-pin in one direction causes theclamps N to move inwardly, and the turning of the screwpin in theopposite direction causing the clamps to move outwardly for maintainingthe bind of the blades Ml against the side of the stock andthroat-plate, or for releasing such bind to permit the adjustment orrelease of the groovingblades.

The opposed sides-oi` the stock A are provided with horizontal ways orgrooves d, in which play projections d4 of the clamp N, permitting theclamps to move longitudinally of the plane-stock, as the blades are socarried when the throat-plate D is moved longitudinally either kto widenor contract the throat.

Having thus described my invention, whatl claim, and desire to secure byLetters Patent, 1s-

1. The combination, with the plane-stock having the pin 1', thev cam J,and the planeiron, of the block G between said cam and plane-iron,having slot q. substantially as described.

2. The combination, with the plane-stock having the pin o', the cam J,and the planeiron, of the block G between said cam and plane-iron,having slot q, and spring s, sub

stantially as and for the purpose described.

3.. The combination,with the recessed planestock having lug m, screw F2,ribbed planeholder F, having lng g, notched plane-iron E, and pivotedcam J, having handle J2, of block G between said cam and plane-iron,having slot q, and spring s, substantially as and for the purposedescribed.

4. The combination, with a planestock having vertically-arrangedrecesses a ai", and the horizontal grooves dad, of the clamping-blocks NN, having dovetailed sockets, inwardly-extending projections (14, andthreaded screwreceiving holes, the right and left threaded screw havingthe intermediate projecting lever, I?, and grooving-knives havingdovetailed edges bearing in said socketed block, substantially asdescribed, for the purposes set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two witnesses.
